ARDUINO UNO

Arduino

is an open source programmable circuit board that can be integrated into a wide variety of makerspace projects both simple and complex.

Microcontroller

This board contains a which is able to be programmed to sense and control objects in the physical world.

Arduino

has become a very popular choice for makers and

makerspaces looking to create interactive hardware projects.

Massimo Banzi

He introduced the Arduino

2005, Italy

when and where was Arduino first introduced

Open-source

it is released under a Creative Commons license, which allows anyone to produce their own board.

• Adafruit

• Sparkfun

Examples of an Arduino clone

LilyPad

is designed to be easily sewn into e-textiles and wearable projects.

Arduino UNO

it remains to be the most actively used and most widely documented on the market.

Reset Button

This will restart any code that is loaded to the Arduino board

Ground Pin

There are a few ground pins on the Arduino and they all work the

same

AREF

Stands for “Analog Reference” and is used to set an external reference voltage

Digital Input/Output

Pins 0-13 can be used for digital input or output

USB Connection

Used for powering up your Arduino and uploading sketches

PWM

The pins marked with the (~) symbol can simulate analog output

TX/RX

– Transmit and receive data indication LEDs

Power LED Indicator

This LED lights up anytime the board is plugged in a power source

ATmega Microcontroller

This is the brains and is where the programs are stored

Voltage Regulator

This controls the amount of voltage going into the Arduino

board

3.3 V Pin

This pin supplies 3.3 volts of power to your projects

DC Power Barrel Jack

This is used for powering your Arduino with a power

supply

Ground Pins

There are a few ground pins on the Arduino and they all work the

same

5 V Pin

This pin supplies 5 volts of power to your projects

Analog Pins

These pins can read the signal from an analog sensor and convert

it to digital
